78、The character class
要迁移文件夹时，右键选择migrate。可以跨项目migrate
创建一个c++类
80、character input
arrow component指示前方.设置网格和动画
81、character camera and springarm
蓝图中的这个选项，对应bUseControllerRotationPitch属性
use pawn control rotation可以在pawn不转动的情况下，只转动弹簧臂
但是这时候按w\s是沿着人物的前方、后方移动，而不是人物转向相机所在的方向移动。
注意 Controller和Capsule是不同物体，所以可能controller转动，但capsule不转动。

}83、control direction
实现角色朝向相机所看的角度移动
-------SlashCharacter.cpp----------
void ASlashCharacter::MoveForward(float Value)
{if (Controller && (Value != 0.f)){//find out which way is forwardconst FRotator ControlRotation = GetControlRotation();const FRotator YawRotation(0.f, ControlRotation.Yaw, 0.f);const FVector Direction = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::X);AddMovementInput(Direction, Value);}
}void ASlashCharacter::MoveRight(float Value)
{if (Controller && (Value != 0.f)){const FRotator ControlRotation = GetControlRotation();const FRotator YawRotation(0.f, ControlRotation.Yaw, 0.f);const FVector Direction = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::Y);AddMovementInput(Direction, Value);}
}movement组件的orient能够让角色面朝移动方向
rotation rate能够改变角色转向移动的快慢
c++实现
----------SlashCharacter.cpp--------
ASlashCharacter::ASlashCharacter()
{// Set this character to call Tick() every frame. You can turn this off to improve performance if you don't need it.PrimaryActorTick.bCanEverTick = true;bUseControllerRotationPitch = false;bUseControllerRotationYaw = false;bUseControllerRotationRoll = false;GetCharacterMovement()->bOrientRotationToMovement = true;GetCharacterMovement()->RotationRate = FRotator(0.f, 400.f, 0.f);CameraBoom = CreateDefaultSubobject<USpringArmComponent>(TEXT("CameraBoom"));CameraBoom->SetupAttachment(GetRootComponent());CameraBoom->TargetArmLength = 300.f;ViewCamera = CreateDefaultSubobject<UCameraComponent>(TEXT("ViewCamera"));ViewCamera->SetupAttachment(CameraBoom);}
84、hair and eyebrow
新增模块HairStrandsCore
----------MyProject.Build.cs-------
public class MyProject : ModuleRules
{public MyProject(ReadOnlyTargetRules Target) : base(Target){PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "HairStrandsCore" });PrivateDependencyModuleNames.AddRange(new string[] { });// Uncomment if you are using Slate UI// PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });// Uncomment if you are using online features// PrivateDependencyModuleNames.Add("OnlineSubsystem");// To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true}
}
